We sought to create a transcervical chorionic villus sampling model for teaching that would mimic a lifelike model. A model was created using silicone resembling the maternal interface. A cervix with an endocervical canal able to accommodate a catheter and a vagina was also created. Tap water was used as the amniotic fluid. Chorionic villus sampling was accomplished using this model with the actual ultrasound machines and environment as in the real model. This simulator allowed placental placement in different locations to increase the difficulty level as well as angulations and catheter handling. Given the low cost (less than $200), this model could be used indefinitely in a relaxed and controlled environment.

我们试图创建一个模仿逼真模型的经颈绒毛膜绒毛采样模型进行教学。使用类似于母体界面的有机硅创建了一个模型。还创建了具有宫颈内管的子宫颈,该子宫颈能够容纳导管和阴道。自来水被用作羊水。与实际模型一样,使用该模型与实际的超声机器和环境一起完成了绒毛膜绒毛采样。该模拟器允许胎盘放置在不同的位置,以增加难度水平以及角度和导管处理。考虑到低成本 (低于200美元),该模型可以在宽松和受控的环境中无限期使用。
